I'm having this issue on Maverick, however it seems to be an issue with the nvidia drivers more than the flash player. While googling this I found many people with the same issue (albeit with intel cards) , all referencing this bug;
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/314928 I figured it was a long-shot, but sure enough, the output of "lspci -v -s 01:00.0" gives me: 01:00.0 VGA compatible controller: nVidia Corporation G94M [Quadro FX 2700M] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 30ec Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at d2000000 (32-bit, non-prefetchable) [size=16M] Memory at c0000000 (64-bit, prefetchable) [size=256M] Memory at d0000000 (64-bit, non-prefetchable) [size=32M] I/O ports at 7000 [size=128] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: nvidia Kernel modules: nvidia-current, nouveau, nvidiafb While "cat /proc/mtrr" gives me: reg00: base=0x0ffe00000 ( 4094MB), size= 2MB, count=1: write-protect reg01: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back reg02: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back reg03: base=0x100000000 ( 4096MB), size= 1024MB, count=1: write-back reg04: base=0x13c000000 ( 5056MB), size= 64MB, count=1: uncachable reg05: base=0x0b9d70000 ( 2973MB), size= 64KB, count=1: uncachable So I tried adding the memory using the command suggested in the intel bug, as root: echo "base=0xc0000000 size=0x10000000 type=write-combining" > /proc/mtrr The result is flash now plays at decent speed even in fullscreen. Mouse input is still a tad unresponsive, but it's nothing compared to before and it seems to get better the longer you keep it going for some flash videos. For example, auditorium (http://www.playauditorium.com/) is only slow the first 2 levels or so, after that it's very responsive. -- flash player fullscreen - very slow with nvidia proprietary drivers https://bugs.launchpad.net/bugs/218483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
